.To aZZ whom it may concern:

Be it known that I, WILLIAM C. METZNER, a citizen'of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Stove-Grates; and Idahereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference. marked thereon,which form a part of this specification.

This invention relates to stove-grates made of overlapping adjustablesections, whereby the dimensions of the grate may be varied,

and the subject-matter of this application is taken, as a division, froman application for I Letters Patent filed by meDecember 19, 1888,

Serial No. 294,097. The grate herein shown is'a stationary grate to beplaced in the firepot of cook-stoves and having at its front an upwardextension.

In the accompanying drawings, Figure 1 is a bottom View of a grateembodying my invention. Fig. 2 is a top view of the section of the grateshown in' Fig. 1, the sections being separated. Fig. 3 is a section inline a: so

of Fig. 1, the grate being right side up and in its relation to thefront wall and bottom of the fire-chamber. Fig. 4 is a section in line ww of Fig. 3, the grate being right side up.

A Ain the several figures are the sections of the grate' Each suchsection has a longitudinal mid-rib A. On the outer side of each suchmid-rib there is a series of transverseribs A and on the inner side ofsuch mid-rib there is a series of transverse ribs A one standingopposite every alternate rib A and the ribs A of one section alternatingin spacing with those on the other section, as shown in Fig. 3. Theseribs A are all set downward far enough to bring their upper faces even,horizontally,- with the lower faces of the ribs A and mid-rib A. Theribs A of one section may, therefore, extend between the mid-ribs A andribs A of the other section. The said sections may be moved back andforth upon each other for adjustment for the width of the grate, andsaid sections may the lower side of said ribs below the plate B,

and from the bot-tom of which projects a foot C. Said bolt whentightened draws said cap and plate together, and the sections A A arethus bound to each other and the grate is -made a firm body.

plates may, obviously, be placed wherever it is desired to have the feetC.. The lower ends of said feet may be provided with breaking-grooves 0.At the front the ribs A are extended forward and upward and united by atransverse web (1. and said web is provided with breaking-notches a tocorrespond with similar breaking-notches on the mid-ribs A. A curvedface-plate D is applied to the inner face of the upward extensions ofthe ribs-A by means of bolts D, passing through said plate and betweensaid ribs, the heads or the nuts of the bolts engaging said ribs A Saidbolts may be moved up or down between said ribs to raise or lower saidplate to fit it to the fire-pot. Said plate D may also have break-'ing-notches d at its ends.

S, Fig. 3, is a portion of the front wall of the fire-pot.

S is a portion of the door-opening in front of the lower portion of thegrate.

S is a portion of the bottom of the firechamber. Said figure showshow'the grate is supported. At the rear the foot 0 rests upon the floorS and supports the rear por- 0 tion of the grate. At the front theface-plate D forms a support for the grate. Said plate rests against thefront wall S, as shown by the figure. From an inspection of said figureit will appear that both these supports of the grate are adjustable andthat the body of the grate is also adjustable as to width. In placingthe grate into position in the fire-pot these three adjustments may beused.

Breakinggrooves have been heretofore used 1 00 A cap B lies upon theupper sur- 55 Said caps, bolts, and 6 5 in Steve parts; hence I do notlay claim to the same broadly.

I claim as my invention 1. In an adjustable stove-grate, the combination of the sections A A, each having on the side adjacent to theother the ribs A said ribs of one section alternating in spacing withthose on the other section and extending beneath the other section,andone of said sections being extended forward and upward, feet forsupportingthe rearof said grate, and bolts for securing said feet andsections to each other, substantially as shown and described.

2. In a stove-grate, the combination of two horizontally-adjustablcgrate-sections constituting the main portion of the grate, adjustablefeet forming an adjustable support at the rear of the grate, and anadjustable faceplate at the front of the grate for the support of thefront of the latter, substantially as shown and described.

In an adjustable stove-grate, the combination of the sections A A, eachhaving on the side adjacent to the other the ribs A said ribs of onesection alternating in spacing with those onthe other section andextending beneath the other section, bolts to secure said sections toeach other, one of said sections having an upward extension, and aface-plate bolted ad justably to the upper portion of said upwardextension, su bstantially as shown an d described.

In testimony whereof I affix my signature, in presence of two witnesses,this 2lst day of June, in the year 1889.

WILLIAM C. ME'IZNER.
